TORPEDO-DEFENSE.

Specification of Letters Patent.

Patented July 6, 1920.

Application filed April 24, 1918, Serial No. 230,514. Renewed April 16, 1920. Serial No 374 492 To all whom it may concern:

Be it known that I, Eosnnr NAZZARENO, a citizen of the United States, residing at Telluride, in the county of San Miguel and State of Colorado, have invented certain new anduseful Improvements inTorpedo- Defense, of which the following is a specification.

This invention is a method of protecting the hulls of boats from torpedoes or attacks by submarine boats wherein an explosive is carried at a suitable distance from the hull of the carrying boat so. that it may come in contact with a'torpedo or submarine boat at a sufficient distance from t -e hull to prevent damage thereto. 7

One object of the invention is to provide a pivotally mounted hollow arm that carries at its outer end a suitable explosive that may be exploded by means of an electric current.

Another object of the invention is to provide a chamber adjacent the inner or pivotally mounted end of the arm to serve as an expansion chamber when the arm is connected to a suitable source of compressed fluid so that after the explosion of the explosive at the end of the arm the water will be prevented from entering.

A further object of the invention is to provide suitable braces extending from the sides of the hull of the body that will serve to hold the arm at such an angle thatthe explosive will be immersed to a suitable distance from the surface of the water and be maintained at a sufficient distance from the sides of the boat.

bombs or explosives, said circuits being suitably connected with a source of electric energy so that the bombs or explosives may be exploded at will, said fluid pipe being connected to the suitable source of compressed fluid so that the same may be forced into the expansion chambers and the hollow arms to prevent water entering the arm after the bomb or other explosive has been exploded, and bracing means cooperatin with the expansion chambers for maintain ing the bomb or'other explosive at a suitable d1 stance from the side of the hull and providing for the immersion of said bomb or other explosive at a suitable depth.

One practical form of construction and assembly wlll be described and illustrated in the accompanying drawings, in which:-

l igure 1 is a side elevation of one of the arms attached to the hull of a boat and showing the bomb immersed in the water,

F 1g. 2 1s a partial top plan View showlng a port1on of the deck with two of the arms extending outward therefrom.

In the preferred embodiment about to be descr bed, the deck A has mounted therein a fluid pipe 5 that may be secured to the deck by means of the cleats or clamps 6, T, and 8, as shown in Fig. 2. At suitable ntervals the pipe 5 is provided with T oints 9 and 10. These joints are preferably rotatably connected with the pipe 5 and are connected by means of a short length of pipe to the larger diameter sections of pipe 11 and 12.

These larger sections of pipe 11 and 12 are adapted to serve as expansion chambers. Their other ends have connected to them suitable lengths of pipe 13 and 14: carrying at their outer ends the bombs 15 and 16 shown more particularly in Fig. 2. The p1pes l3 and 1d are also hollow and communicate with the expansion chambers 11 and 12 that are connected respectively to the T joints 9 and 10. In order to explode the bombs 15 and 16 suitable circuit wires indicated at B and C are passed through one end of each of the expansion chambers 11 and 12 and extend downward through the hollow arms 13 and 14 to the bombs 15 and 16.

These circuit wires 13 and C may be connected to the feed wires D that are connected with a suitable source of electric outward from the side E of the hull should be suificient to position the bomb 15 at a suitable distance from said side of the hull. At the same time this brace should be of suflicient length so that the bomb 15 may be immersed a suitable distance from the surface of the water so that it may engage with an oncoming torpedo or submarine boat.

The distance that the bomb 15 is disposed from the boat should be great enough so that when the explosion occurs it will not damage the hull of the carrying boat. In Fig. 2 only two of the arms and their connections are shown but in equipping a boat these arms would be spaced around the hull so as to form an effective barrier.

After the explosive has been fired the wires in the hollow arm will naturally be exposed and it is to prevent short circuiting of the wires that I admit compressed air into the arms to prevent water from entering.

lVhat is claimed is:

1. A torpedo defense for boats, which comprises a plurality of pivotally mounted hollow arms carrying a bomb at their outer ends, enlargements formed on the inner portion of the arm, means for admitting fluid to the enlargements and arms, and electrical means for exploding the bombs.

2. A torpedo defense for boats, which comprises a fluid pipe secured to the deck of a boat, a plurality of spaced rotatable T joints in said pipe, an expansion chamber connected with each of the joints, a hollow pipe connected to the other ends of each of the expansion chambers and serving as a conduit, an explosive carried at the outer ends of each one of these hollow pipes, and electric circuits passing through the expan sion chambers and through the hollow pipes to the explosive, and adapted to convey current for causing an explosion of the explosive.

3. A torpedo defense for boats, which comprises a fluid pipe secured to the desk of a boat, a plurality of spaced rotatable arms connected with said pipe and carrying at their outer ends suitable explosive, an electric circuit passing through each one of the hollow arms and connected with the explosive, the inner ends of each of the hollow arms being enlarged to form expansion chambers and means for positioning the arms at a suitable angle with the side of the hull, said means having a forked end that is adapted to en age with the expansion chamber carried by the hollow arm.

In testimony whereof I afiix my signature in presence of two witnesses.
